Solution
The correct option is A gain
Non-metals have nearly filled electron shells, requiring only a few additional electrons to assume the stable, noble-gas configuration. Therefore, in the presence of other atoms, these nonmetallic atoms have pronounced tendencies to attract electrons to themselves (high electronegativities). They form chemical compounds by attracting electrons away from other atoms of lower electronegativities or by sharing electrons with atoms of comparable electronegativities.
